[0' all-whom it may concern.'.

Be'it known that HUco GALLR, deceased, late a citizen of'the German Republic, re-' "siding at Goesfeld, (,ierinany. has invented certainnew and useful Improvementsin Traveling .or Chain-Grate Stokers, of whieh the following is a specification;

'-'The invention is directed'to a breaker bar for use in connection with chain grate stokers. Inorclinary traveling stokers a clinker. dam is placed at the end thereof to retain the clinkerson the "grate appreciably to permit the elinkersto be more or less fullyburnt out. 1 ..As ordinarily provided, this construction results in difficulties largely through the fact that by the retention of the clinkers throughthe, use of; thedam such,

clinke'rs will unite to I forinlarge clinker cakes,"which-cannot pass the/dam and thus bank up. and hold back the smaller clinkers from passing The present invention. aims to overcome this difiicult'y by providing oneor more breaker. barsi arraijiged transversely of and in close proximity to the grate With-means for oscillating the bars transverse the grate to breakup-the clinkers and prevent-the bars in section.'

formationof tlie'lai'geiclinker cakes. I f I The invention .is illustrated inthe accom: panying'd-rawings-in whieh:

In thedrawings 1 represents. diagram- "matically traveling grate on which are arranged brealierbars 2..and 3, the latter being-placed immediately in front of the usualclinlier dam 4. These bars are ar- -rangedin close proximity to the grate and I e are adapted to be reeiprocated transversely of thegratethiioiigh the medium .of lever invention, If desired, thebreaker bars na'y mechanism, indicated generally atlfr, thedetails of Which form no part of the present 1925.

be formed with inner channels through of'the grate. This maintains constant agitation of the fuel, preventsthe formation of excess clinkers and increases the capacity of the grate, as the constantly moving fuel permits more lively combustion. If desired, as indicated infFig. 2 the forward edge of one or both, of the breaker bars may'be given a serrated or wavy formationgas' indicated 7 to facilitate the breakingffip and stirring of the clinkers'. I cla1m:-

1. The combination with a, traveling grate of a breaker bar arranged transversely of and in close proximityto the grate/and formed and arranged to present a raking edge towards the advancing fuel, and means for reciprocating said breaker-bar trans-'" versely ofthe grate.

2.- The combination with a traveling grate, of a plurality of breaker bars dis.-,.

tributed in spaced parallel relation trans verselyof and in close proximity to the grate, sa1d bars being arranged and formed. .tjo'present a raking edge to the advancing fuel, and means for simultaneously reciprocating said bars transversely of the grate.

3. The combination withv a traveling grate of a breaker bar arranged transversely of and in close proximity to the grate and formed and'arranged to present a raking; edgetowards the-advancmg fuel, and means J for rec p-rocatlng said breaker bar transversely of the grate, said bar being interiorly ing fluid therethrough.
